v 3 Claims. (Cl. 117-2) This invention relates to a method and means for treating yarn so that the yarn can be given a greater amount of twist, that is a greater number of twists per inch, and still so prepare the yarn that it will not kink. Heretofore, the number of turns per inch which can bel imparted to yarn in the twisting operation is limited due to the fact that after a certain maximum of turns per inch has been reached, the yarn will kink,l thus forming an imperfect product.

An object of this invention isto provide amethod and means for treating yarn in the twisting operation by lubricating the yarn thus providing a heavier thread and allowing the use of a heavy traveler to draw in the yarn tauter than has heretofore been accomplished. The weight of the lubricated thread permits more twist to be imparted to the thread without causing the thread to kink. The method is especially adapted for preparing sewing thread.

I am aware that heretofore various vmethods,

and means have been employed for the treating of yarn, thread, and the like by subjecting the thread to a bath containing an adhesive or gum, but the primary object of my invention is to subject the yarn prior to the twisting operation t0 a bath of lubricant to lubricate the thread and therefore to attain the objects enumerated.

The invention broadly contemplates the passing of' strands of yarn into a suitable solution, comprising a lubricant or lubricants in said solu-4 tion and then drying the yarn by any suitable means such as the passing of the yarn over.

heated'members such as steam pipes and then if desired the yarn can be passed over a suitable support with a positively driven brush for brushing the fibers in alinement with the longitudinal axis of the yarn and then passing the strands of yarn thru the conventional 'twisting rollers and thru the traveler to wind the thread onto suitable bobbins, after the strands -are twisted.

By the use of the improved method and means as herein set forth, it has been foundA that the tensile strength of the thread is increased great. vly and that a given length of staple can be used to provide a thread fully 25'per cent stronger than a thread manufactured in the conventional manner from the same length of staple as the lubricant permits' greater twist to be imparted to the .thread and permits a heavier traveler to setlthe'twist without kinking and the lubricant also causes the bers t0 adhere to the outvsuch as' supports 42, and these troughs extend side surfaces of the thread to cause the thread to have an appearance similar to that of thread made from single yarn.

Some of the ,objects of the invention having been stated, other objects will appear as the description proceeds when taken' in connection with the accompanying drawings, in which- Figure 1 is an' end View of a twisting frame equipped with means for carrying out my improved method;

Figure 2 is a side elevation of a twisting frame as shown in Figure 1;

Figure 3 is a vertical sectional view thru the tank for supplying the lubricating solution;

Figure 4 is an enlarged cross-sectional View takenthru one side of a twisting frame and showing the means for performing the hereinafter explained method;

Figure 5 is an enlarged detail view in elevation showing the mounting for the guide rollers or shafts associated with the steam pipes;

Figure 6 is a cross sectional view taken along the line 6-6 n Figure 5;

Figure 'l is a detail of one end of the rollers or shafts for guiding the thread with relation to the steam pipes.

V(not shown) are passed from drum 15 for driving the spindles. The spindles are adapted to receive suitable bobbins' 21 on which the body of thread 22 is wound, the thread passing from creels 24 supported on the pins 25 mounted on supports 26 on creed frame supports 271 The spinning frame is also equipped with guides 29 and feed rollers 30 and 31.

The above described parts are conventional and cooperating with these parts are the other features of the means for performingthe method hereinafter explained. These features are the providing elongated troughs 40 on each side of the twister supported by any suitable means upwardly and outwardly as at 43 to a greater extent than to the troughs heretofore used.

1 provide a bracket 45 secured yto vertical sup ports 27 on each side of the frame in which I secure a shaft/46 and on shaft 46 at spaced 10 intervals, I secure supports 48 by anysuitable means such as a set screw '49. These supports 48 serve not only to support the rod `or roller 50 for causing the strands of yarn 5l and 52 to be submerged in the lubricating solution 54, but these brackets also support rollers or rods 55 and 56 which rollers or rods are mounted -in suitable slots 57 and 58 respectively, and are adjustably secured in said slots by means of bearing members 59 being adjustably secured by nut 60. threadably'engaging the bearing which penetrates the slot and into which the bearing portion 61 of rods or rollers 55 or 56, as the case may be, are adapted to t.

Each of brackets 48 has a downwardly pro- -`iecting portion 63 which rests on the bottom oi' trough for assisting in the supporting of said brackets. Said brackets also have secured therein steam pipes 65 and 66, the pipe 86 being connected to a pipe 67 leading from a source of steam supply and after pipe 66 traverses the entire length of its respective trough, it is bent upon itself and led back to the other end of the trough, the lowerI portion being indicated by reference character 65.` Pipe 65 is led from the end of the trough and is connected to a' pipe 69 which leads to a suitable trap or other exhaust means.v

Mounted on top of the railway head or in any other suitable position is a tank 70. which is shown open at its upper end, but which may be covered if desired. A Pipe 71 leads from steam supply pipe 67 thru tank 70 in the form of a coil 72 and has exhaust pipe 73 which is led to any suitable trap or other conventional means for regulating the passage of steam thru coil 72. The purpose of this arrangement is to heat the lubricant to break down said lubricant and to cause it to adhere to and penetrate the yarn. A pipe 75 is led from near the bottom of tank 70 and has branches 76` and 77 having suitable valves 78 and 79 therein for regulating the flow of fluid from tank 70 into the troughs 40`. In the other-ends of troughs 40` upper and lower pipes 80 and 81 penetrate the end wall of each of said troughs with pipe 81 having" valve 82 therein which may normally be closed or opened any desired amount, and these pipes 80 and 8l are connected to a pipe 84 which leadsto one side of a pump 85 driven by any suit-v able means'such as an electric motor 86 and from the other side of pump 85 a pipe 87 is led beneath the machine and empties into tank 70 as at 88. It is thus seen that lubricant is heated and poured into one end of the tanks and is withdrawn as fast as desired. from the other end of the tanks normally into overflow pipe 80 and also into a pipe 81 if desired and is passed thru pump 85 where it is broken up and passed on into tank where it is again heated and thus thel lubricant is supplied to the trough of the proper temperature to properly penetrate and adhere to the strands of yarn as they are passed beneath rod or roller 50.

If desired, I can provide suitable supports 90 as shown in Figure 4 but omitted in Figures 1 and 2 for supporting member 91 across which the thread is passed, and a brush 92 may be mounted above support 91 extending' all the way across the machine and which is positively driven from the machine by means; not shown,

vthe direction ofrotation being indicated by the normes arrow in Figure 4 and .when this brush is used it will aid in the alinement of the ilbers which project from the yarn to cause them to stick to the yarn to render the yarn smoother and stronger than heretofore, and when the strands of `yarn are passed on into the twisting operation, the rollers 30 and 31 will assist in setting the surface bers into the surface of the yarn and in this positionthe surface ii-bers will assume a position which is parallely to the longitudinal axis of the thread;

It is thus seen that by use of the above means the yarn can be treated to provide a thread to which a greater amount to twist can be imparted Without kinking, thus permitting a heavier traveler to be used to draw the thread on bobbin 22 tauter than has heretofore been possible, thus setting the twist and eliminating the possibility of any kinks due to the use of the lubricant, and thus providing a thread much. stronger and smoother from a given length of staple than has heretofore beenpossible.

Any suitable lubricating bath may be used, but I have found -that a solution of 150 pounds of paraffin wax, 40 pounds of white tallow, one pound of soda ash, 30 pounds of rosin mixed with a solvent, or a like amount of triethanolamine, with enough water added to make a solution oi 50 gallons is suitable in carrying out my method, though it is evident that the ingredients of the bath may be varied to suit individual requirements.

In the drawings, and specification `there has been set forth a preferred embodiment of the invention and although specific terms are employed, they are used in a generic and descriptive sense only and not for purposes of limitation, the scope of the invention being set forth in-the appended claims.

I claim:

l. In a twisting frame having a plurality of supports for packages of yarn and having a vat adapted to contain a treating solution with a member mounted in said vat under which the Vets disposed along the vat for supporting they strands of yarn are passed, a plurality of brackmember, a plurality of steam heated pipes 'mounted in said bracket, means adjustably mounted in said bracket for directing the yarn selectively against said heated pipes, a brush adapted to be positively driven by the machine for brushing the strands of thread after they have passed over the steam heated pipes, and means for directing the strands of yarn tothe ytwisting means.

the twisting means and means for wipingY the strands of thread before the twisting operation.

3. That method of treating cotton yarn comprising subjecting the yarn to a bath comprising a solution of paraln, tallow, soda ash, rosin and a solvent for the rosin, partially drying the yarn and then twisting the yarn.
